If you were dreaming of shopping for clothes, it means you are preparing for an important event. You know you have to dress well to make an impression. Perhaps in your life, you are expecting to attend an event of significance. It can be a social function, or official one like a job interview. If you see yourself buying formal clothes in your dream, then it means you’re preparing for a formal function. If you see dream imagery of buying casual clothes or party clothes, then your dream hints you expect to attend a social gathering.
Other dream interpretations can be triggered by a genuine lack of suitable clothes in your wardrobe right now. Then this dream is a hint to tell you to go shopping for clothes.
